Renowned for their outstanding quality and dependability, Neil Metals crafts these products to comply with strict international standards like ASTM and ASME. Thanks to their cutting-edge manufacturing processes and thorough quality checks, Neil Metals guarantees that their Cobalt Alloy 6B offerings boast excellent corrosion resistance, high-temperature strength, and remarkable wear resistance. Catering to sectors such as aerospace, chemical processing, power generation, and medical equipment, Neil Metals delivers customized solutions that fulfill essential performance needs while ensuring long-lasting durability.
Cobalt Alloy 6B Bars and Rods are primarily made up of cobalt (about 60%), chromium (27%), nickel (5%), molybdenum (5%), along with trace amounts of iron and carbon. This distinctive blend provides exceptional resistance to oxidation, corrosion, and thermal fatigue. On the mechanical side, these alloys exhibit a tensile strength of around 850 MPa, a yield strength close to 480 MPa, and an elongation of up to 30%. Cobalt Alloy 6B retains its strength and stability even at high temperatures, making it perfect for applications that require both high thermal and chemical resistance, as well as mechanical durability.

Welding processes suitable for Cobalt Alloy 6B Bar include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and resistance welding. Preheating and post-weld heat treatment are often required for optimal results.
Yes, Cobalt Alloy 6B Bar can be welded, but it requires careful control of heat and filler material to avoid cracking or weakening. Preheating and post-weld heat treatment are often recommended.
Cobalt Alloy 6B rods are available in various sizes, typically ranging from 0.125" to 6" in diameter. Common finishes include cold-drawn, hot-rolled, and polished for enhanced surface quality.
Cobalt Alloy 6B Bars and Rods find extensive use in industries that demand superior corrosion resistance and strength under elevated temperatures. In the aerospace sector, they are utilized for turbine blades, combustion chambers, and exhaust components. The chemical and petrochemical industries rely on them for reactors, heat exchangers, and valves that face harsh environments. Power plants incorporate these bars and rods in boilers and gas turbines. Moreover, medical devices like implants benefit from their biocompatibility and wear resistance. With their impressive thermal stability and durability, Cobalt Alloy 6B is the go-to choice for industrial applications that deal with extreme heat and corrosive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
